A field trial was conducted to examine genetic variability and heritability in okra germplasm using 21 genotypes arranged in a Randomized Block Design (RBD) with two replications at the Instructional Farm, Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during the summer season of 2024–25. Analysis of variance revealed significant differences among genotypes for all traits under study. Substantial diversity was observed in key yield-related attributes. For each trait, the phenotypic coefficient of variation (PCV) was greater than the genotypic coefficient of variation (GCV). High values of both PCV and GCV were recorded for leaf chlorophyll content, fruit width, number of branches per plant, and fruit yield per plant. Traits including fruit yield per plant, fruit weight, number of fruits per plant, fruit length, fruit width, number of branches per plant, and chlorophyll content exhibited high heritability coupled with high genetic advance over the mean, indicating the predominance of additive gene action. This suggests that these traits can be effectively improved through selection.
